1978年,我们作了杉树针叶扞插育苗试验,最近检查,留少量树皮(即带腋芽)、药物处理及管理较好的试区有40％的成活率,即长出了绿苗又出了根,凡不带腋芽的,只有部份出根而不长苗。现简报加下: 一、扞插季节:春季和秋季效果都好,夏季较差,冬季扦插的,暂时还未看出效果。二、枝条的选择与处理: 在杉木优树集穗圃中剪取半年生的嫩枝,(同一枝条,上部枝比下部枝好)。切削叶片时,关键是叶片基部要带少许树皮,勿伤叶片腋芽部位。我们78年的试验,多数试区的针叶
In 1978, we made fir needle coniferous breeding experiments, the recent inspection, leaving a small amount of bark (ie with axillary buds), drug treatment and better management of the trial area has a 40% survival rate, that is, grow green seedlings Out of the root, where no axillary buds, only part of the root rather than long seedlings. Now briefing added: First, to defend the season: Spring and autumn are good, poor in summer, winter cuttings, yet to see the effect. Second, the choice and treatment of branches: In the Chinese fir clump seedbed cut half-year-old shoots (the same branch, the upper branch than the lower branch good). Cutting blade, the key is to bring a little bark at the base of leaves, leaves do not hurt the axillary bud parts. Our 78-year trial, most of the trial conifer
